Description

Food containers

The present invention relates to a food container capable of packaging food.

Traditionally, as a self-help device used by caregivers and infants, such as weakness of the upper limbs and reduced function, and care tools used by caregivers and guardians of infants, etc., in a shape that assists the act of scooping food with a spoon Formed food containers are known.

As such a food container, for example, Japanese Registered Utility Model No. 3022573 discloses a deep dish with one wall surface vertical and the other wall surface inclined. In such a container, the spoon is brought into contact with one wall surface and moved upward so that food can be easily squeezed, and the operation of the spoon is facilitated by guiding the spoon through the other wall surface. In addition, a technique is known in which a plurality of containers can be stacked on the food container by providing a plurality of ribs in the circumferential direction.

Japanese Patent Application Laid-Open No. 2002-240858 discloses a food container in which one side of the peripheral wall of the container is bent in an arc shape inwardly of the container body, and an easily peelable adhesive is provided on the back of the bottom. ing. Such a meal container can be arranged in a shape that allows easy entry of food into the mouth by pulling up the spoon along the bent peripheral wall. In addition, the meal container can be fixedly placed on the dining table by the easily peelable adhesive on the bottom rear surface. Patent Document 2 also discloses a technique in which a meal container is used as a packaging container for packaging food.

Registered Utility Model No. 3022573 JP 2002-240858 A

The food container described above has the following problems. In other words, the food containers disclosed in Japanese Registered Utility Model No. 3022573 and Japanese Patent Application Laid-Open No. 2002-240858 are circular in top view, so that the insertion side of the spoon is difficult to see at first glance and is visually There was a problem that the nature was bad. Moreover, since these food containers are circular in top view, when the spoon is stood on the periphery of the container, the spoon may move along the periphery and the spoon may fall into the container. For this reason, there is also a problem that it is difficult to take out the spoon when the meal is resumed.

Further, in the food container described in Japanese Patent Application Laid-Open No. 2002-240858, one side of the peripheral wall is bent and formed in an arc shape inward of the container body, so that the moving distance of the spoon becomes long. In addition, the movement direction of the spoon requires a so-called spoon return operation in which the spoon moves in the front direction and then moves in the back direction and the vertical direction.

When using a food container as a care tool, the caregiver or the like uses a spoon, so it is easy to return the spoon, but when using a food container as a self-help tool, return the spoon. It becomes difficult to use the food container. Moreover, since the foodstuff in a container is covered with the surrounding wall formed by bending, there also exists a problem that the visibility of the foodstuff in a container is bad.

Also, the food container described in Japanese Registered Utility Model No. 3022573 requires a rib on the flange when laminating a plurality of food containers, and the configuration becomes complicated. The food container described in Japanese Patent Application Laid-Open No. 2002-240858 describes a configuration in which a rib is provided on the outer periphery of the upper surface and a lid is provided as a packaging container, but the opening area is larger than the bottom area. Since it is a small configuration, there is a problem that it is difficult to stack and the conveyance during manufacture is poor.

For these reasons, there is a demand for food containers with high usability called so-called usability.

Therefore, an object of the present invention is to provide a food container having high usability.

In order to solve the above problems and achieve the object, the food container of the present invention is configured as follows.

As one aspect of the present invention, a circular bottom, a first wall formed continuously with the bottom, and a curved surface and an inclined surface inclined with respect to the bottom, and the first wall A second wall portion extending in a direction orthogonal to the surface direction of the bottom portion formed continuously, one of the openings being a square shape and the other being a semi-elliptical wall portion; And a flange portion formed continuously on the second wall portion.

According to the present invention, it is possible to provide a food container having high usability.

As shown in FIG. 1, the food container 1 includes a container body 2 that holds the food 100 and a lid body 3 that seals the container body 2. The food container 1 is used as a self-help tool and a care tool. The food container 1 is a food packaging container in which the food 100 is packaged in an airtight manner by the container body 2 and the lid body 3.

The container body 2 is a container that wraps the food 100 together with the lid 3 and holds the food as a self-help tool and a nursing tool after the lid 3 is removed. As shown in FIGS. 1 to 6, the container body 2 includes a bottom portion 11, a wall portion 12, and a flange portion 13. The bottom part 11 is formed in a circular shape. The center of the bottom portion 11 is eccentrically arranged on one side from the center of gravity (center) of the flange portion 13 and the second wall portion 22 described later in the top view shown in FIG.

The wall portion 12 and the flange portion 13 are formed in a square shape on one side from a boundary position between a rectangular portion 24 and an elliptical shape portion 25 (to be described later) of the flange portion 13 in the top view shown in FIG. It is formed into a shape. Further, as shown in FIG. 4, the wall portion 12 and the flange portion 13 are longitudinally extended from the center of the flange portion 13 to the respective ends on the rectangular side and the elliptical side, as shown by a two-dot chain line in a semi-elliptical symmetrical shape. The lengths in the direction are substantially the same.

The wall portion 12 is formed continuously with the bottom portion 11. As shown in FIGS. 2, 3, and 5, the wall portion 12 is formed between the first wall portion 21 formed from the bottom portion 11 with a predetermined curved surface and an inclined surface, and the upper end of the first wall portion 21 and the flange portion 13. The 2nd wall part 22 which continues.

The first wall portion 21 includes a rectangular portion 24 formed on one side in a square shape when viewed from above with the bottom portion 11 interposed therebetween, and an elliptical shape portion 25 formed on the other side in a semi-elliptical shape when viewed from above. I have. The rectangular part 24 and the elliptical part 25 are formed to have the same height from the bottom part 11 to the upper end part.

The outer periphery of the upper end of the rectangular parallelepiped portion 24 is continuous with the elliptical portion 25 in a top view, and is orthogonal to the two straight portions forming a pair of lateral ends and the lateral straight portions. A rectangular shape is formed by the continuous linear portion forming the end.

The rectangular portion 24 is formed by a curved surface from the bottom 11 to its upper end. The rectangular portion 24 is formed with a curved surface having a predetermined curvature from an end portion continuous with the bottom portion 11 to an end portion continuous with the second wall portion 22.

The elliptical portion 25 is formed with a curved surface having a predetermined curvature at the end continuous with the bottom portion 11, and the main surface direction of the bottom portion 11 extends from the middle portion to the end continuous with the second wall portion 22. It continues by the inclined surface which makes a predetermined angle.

Note that the rectangular portion 24 is formed so that the curvature thereof is smaller than the curvature of the curved surface of the elliptical portion 25. In other words, the curved portion 24 is formed so that the curvature radius of the curved surface is larger than the curvature radius of the curved surface of the elliptical shape portion 25.

Further, the first wall portion 21 is formed such that the distance from the bottom portion 11 to the outermost peripheral end portion of the elliptical portion 25 is shorter than the distance from the bottom portion 11 to the outermost peripheral end portion of the rectangular portion 24. The first wall portion 21 has at least a second wall that is inclined more continuously from the upper end to the bottom 11 of the elliptical portion 25 than the inclined surface that continues from the upper end to the bottom 11 of the rectangular portion 24. A large inclination angle is formed on the portion 22 side.

The first wall 21 has a rectangular portion 24 continuous from the center of the bottom portion 11 to one side and an elliptical portion 25 continuous from the center of the bottom portion 11 to the other side. Further, in the first wall portion 21, a rectangular portion 24 is continued on one side from an approximate center in the longitudinal direction of the second wall portion 22, and an elliptical portion 25 is continued on the other side.

That is, at the upper end of the first wall portion 21, the distance from the boundary position of the rectangular portion 24 and the elliptical portion 25 to the outer peripheral ends of the rectangular portion 24 and the elliptical portion 25 is formed to be the same, In the bottom portion 11, the distance from the center of the bottom portion 11 to the outer peripheral end of the elliptical portion 25 is shorter than the distance from the outer peripheral end of the rectangular portion 24.

The second wall portion 22 is formed continuously with the first surface portion 31 formed at the upper end of the first wall portion 21 and the first surface portion 31, and extends in a direction orthogonal to the surface direction of the bottom portion 11. Second surface portion 32.

The first surface portion 31 is formed continuously from the upper ends of the rectangular portion 24 and the elliptical portion 25 along the surface direction of the bottom portion 11. The first surface portion 31 is formed such that when the container body 2 is laminated, the lower surface thereof can come into contact with the upper surface of the flange portion 13 of the other container body 2. The first surface portion 31 is formed so that the wall portion 21 can be separated from the wall portion 21 of the other container body 2 when contacting the flange portion 13 of the other container body 2.

The flange portion 13 is formed continuously at the upper end of the second surface portion 32 of the second wall portion 22 and is formed along the surface direction of the bottom portion 11. The flange portion 13 is formed on the upper surface thereof so that the lid 3 can be fixed by adhesion, pressure bonding, welding, or the like. Note that the outer peripheral edge of the flange portion 13 may be partially cut away so that the outer peripheral edge of the fixed lid 3 is separated from the upper surface of the flange portion 13.

The lid 3 covers the flange portion 13 and is fixed to the flange portion 13 so that the space formed by the bottom portion 11 and the wall portion 12 can be sealed. The lid 3 is made of, for example, a resin material or aluminum foil. For example, the lid 3 is formed in a film shape with a resin material such as polyethylene or polypropylene.

The food container 1 configured in this manner has the elliptical portion 25 arranged on the side opposite to the user's dominant arm side, and a spoon for the food in the container body 2 is inserted from the rectangular portion 24 side, and In other words, the spoon is moved from the square shape portion 24 toward the oval shape portion 25, in other words, from the dominant arm side to the opposite side of the dominant arm side.

More specifically, the food container 1 is formed by the rectangular portion 24 and the elliptical portion 25 of the first wall portion 21 so that the container body 2 is formed in a rectangular shape in the longitudinal direction when viewed from above, and the other is It is formed in an elliptical semicircular shape when viewed from above. In addition, the rectangular portion 24 of the first wall portion 21 is formed so that the inclination angle to the bottom portion 11 is gentler than that of the elliptical portion 25 and the length of the inclined surface of the first wall portion 21 is longer. The

For this reason, the opening area of the container body 2 on the side of the rectangular portion 24 is larger than the opening area of the elliptical portion 25, so that the spoon can be easily inserted into the container body 2. For this reason, the spoon is inserted from the opening on the rectangular portion 24 side of the container body 2.

In addition, the square portion 24 has a longer distance to the bottom portion 11 than the elliptical portion 25, and the inclination angle is small. That is, the rectangular portion 24 is formed more gently than the elliptical portion 25, and when the spoon brought into contact with the upper surface of the rectangular portion 24 is moved to the bottom portion 11, the spoon in the surface direction of the bottom portion 11. The movement amount of the spoon in the vertical direction may be small with respect to the movement of.

For this reason, it is not necessary to press the spoon excessively on the upper surface of the rectangular portion 24 by moving the inserted spoon to the bottom portion 11 in contact with the upper surface of the rectangular portion 24. 24 It is possible to move to the bottom 11 while being in contact with the top surface. Since the spoon moves continuously from the rectangular portion 24 in contact with the upper surface of the bottom portion 11, the spoon moves to the bottom portion 11 while scooping a part of the food located in the traveling direction of the spoon on the rectangular portion 24. Is done. In addition, a part of the said food which is not squeezed by a spoon moves with the movement of a spoon by being pushed by the food squeezed by the side surface and the upper surface of a spoon.

Next, when the spoon is further moved while being in contact with the upper surface of the bottom part 11, the spoon crawls a part of the food located in the traveling direction of the spoon on the bottom part 11. In addition, a part of the said food which is not squeezed by a spoon moves with the movement of a spoon by being pushed by the food squeezed by the side and upper surface of a spoon.

Furthermore, when the spoon is moved, the spoon moves from the bottom part 11 to the oval part 25. The elliptical portion 25 has a shorter distance from the bottom 11 to its end than the rectangular portion 24 and the inclination angle is greatly inclined, so that the spoon is further moved along the elliptical portion 25. By doing so, the spoon is guided to the end of the elliptical portion 25. Thereby, even if it does not return a spoon, a spoon moves upwards and the other part of the food pushed by a spoon moves to the upper surface of a spoon by the inclination angle of the elliptical part 25.

Further, when the spoon is further moved, the spoon moves from the first wall portion 21 to the second wall portion 22, and the spoon moves upward along the second wall portion 22. By this movement, the food pushed by the spoon and the food on the spoon is guided by the second wall portion 22 and moved onto the spoon. For this reason, even if it does not perform the operation | movement which returns a spoon, it becomes possible to scoop the foodstuff in the container body 2 with a spoon.

According to the food container 1 configured as described above, one side is formed in a square shape with the bottom 11 being sandwiched, and the other is formed in an elliptical shape, so that the opening area on one side is large, in other words, the end on one side. Since the width of the part becomes large, it becomes easy to move the spoon into the container body 2. Moreover, since the side which moves a spoon in the container body 2 is a square shape and a wide width | variety, and the container body 2 is formed in the square shape from the shape where the width | variety is wide, it looks like a spoon at a glance. You can see the insertion side. That is, the food container 1 has good visibility and recognizability such as the moving direction of the spoon of the container body 2.

In addition, the container body 2 is formed by a curved surface with a gentle inclination angle of the rectangular portion 24, and the distance from the end of the rectangular portion 24 to the bottom portion 11 is long. It becomes easy to move to the bottom part 11 along the upper surface of the rectangular part 24.

In addition, the food container 1 is formed such that the inclination angle of the elliptical portion 25 is larger than that of the rectangular portion 24, and the distance from the bottom 11 to the end of the elliptical portion 25 is short. . For this reason, by moving the spoon along the upper surface of the oval-shaped portion 25, the spoon is positioned below the spoon and the food that is moved on the spoon. It can be positioned on the upper surface.

In addition, the container body 2 is provided with the second wall portion 22 extending in the direction orthogonal to the bottom portion 11 at the upper portion of the first wall portion 21, so that the spoon that has moved the elliptical portion 25 has the second wall. Since it moves upward along the part 22, it becomes possible to scoop up food that is pushed and moved by the spoon without the action of returning the spoon.

As described above, the food container 1 can guide the movement of the spoon and guide the food in the container body 2 onto the spoon by the shape of the wall portion 12. Further, the food container 1 guides the movement of the spoon by the shape of the wall portion 12, so that the food can be squeezed by the spoon without the need for the spoon returning operation.

In particular, when used as a self-help tool, it is often difficult to precisely move the spoon and move the spoon back. However, the food container 1 has high usability as a self-help tool or a care tool by guiding the spoon and moving the food onto the spoon depending on the shape of the wall portion 12.

Further, since one side of the container body 2, that is, the rectangular portion 24 side of the first wall portion 21 is formed in a square shape in a top view, the peripheral edge of the second wall portion 22 is linearly arranged. The For this reason, when resting a meal and placing a spoon on the container body 2, it is possible to place the spoon stably by leaning the spoon against the second wall portion 22 on the square portion 24 side. It becomes possible.

Specifically, the case where the spoon is stood and placed on the container body 2 will be described. When the inner peripheral edge is curved like the second wall portion 22 on the oval shape portion 25 side, the portion that contacts the container body 2 at the tip of the spoon and the container body 2 at the gripping portion of the spoon come into contact. There is a high possibility that the continuous line of the part is displaced from the direction perpendicular to the tangent plane of the curved inner periphery with which the spoon contacts. If the continuous line of the spoon deviates from the direction perpendicular to the tangential plane of the inner peripheral edge, the spoon may rotate along the inner peripheral edge of the second wall portion 22 around the contact portion at the tip of the spoon.

On the other hand, the second wall 22 on the side of the square part 24 is linearly extended by placing the spoon on the second wall part 22 on the side of the square part 24 and placing it on the container body 2. Therefore, there is no possibility that the spoon rotates. For this reason, the container body 2 can place the spoon stably.

Further, the container body 2 is formed when the first surface portion 31 of the second wall portion 22 is laminated with another container body 2, specifically, as shown in FIGS. 7 and 8. In addition, it is formed so as to be able to contact the upper surface of the flange portion 13 of the container body 2 located in the lower stage. For this reason, the container body 2 can be stacked and transported when packaging food, and the transportability is good. The container body 2 does not require a rib or the like and may have a simple configuration.

Since the container body 2 has its first surface portion 31 and the flange portion 13 of the other container body 2 in contact with each other, the pressure receiving area can be ensured when a plurality of the container bodies 2 are stacked. As a result, deformation due to its own weight can be prevented as much as possible, and stable lamination can be performed.

Further, since the first container 31 and the flange 13 are in contact with each other on the surface along the bottom 11, that is, the surface orthogonal to the direction of gravity, the laminated container body 2 receives a force in the gravity direction due to its own weight. Even if it is applied, the separation of the stacked container bodies 2 is not hindered. In other words, the container body 2 is a container to be laminated because the wall portion 12 does not contact the wall portion 12 of the other container body 2 even if the first surface portion 31 contacts the flange portion 13 of the other container body 2. It becomes possible to prevent the wall portions 12 of the body 2 from being fitted to each other. Thereby, separation of the laminated container body 2 becomes easy.

Further, the food container 1 has the flange portion 13 in the container body 2, whereby the lid body 3 can be fixed to the container body 2. Thereby, the container 1 for foodstuffs comprises the packaging container which can seal and package a foodstuff.

Moreover, the container body 2 can improve the strength by having the flange portion 13. In addition, the container body 2 can disperse an external force depending on its shape on the elliptical side, and has higher strength than the rectangular side. That is, the bottom 11 has a circular shape, and the center of the bottom 11 is eccentric to the elliptical side with respect to the boundary between the elliptical part 25 and the rectangular part 24, so that the first wall 21 on the elliptical side has an upper surface. It becomes an arch shape or an arc shape when viewed, and the strength is higher than that of the rectangular side.

In particular, the container body 2 has a configuration in which the elliptical side is positioned on the user's dominant arm side, and when the hand is held with a spoon, the elliptical side may be gripped, whereby a force may be applied to the elliptical side. There is. Moreover, the container body 2 may have a mouth depending on its shape and usage.

For this reason, the container body 2 can prevent the deformation of the container body 2 during use as much as possible by setting the elliptical shape side to have a higher strength than the square side.

Moreover, the container body 2 makes the square-shaped part 24 of the 1st wall part 21 into the curved surface of predetermined | prescribed curvature, increases a contact area with the curved surface of the bottom face of a spoon, hold | maintains a spoon reliably, It can be moved stably. Thus, the container body 2 can operate a spoon smoothly.

As described above, according to the food container 1 according to the embodiment of the present invention, the visibility of the insertion side of the spoon is improved by making one of the bottoms 11 a square shape and the other a semi-elliptical shape in a top view. It is possible to widen the opening width into which the spoon can enter. Moreover, by making the square-shaped part 24 of the 1st wall part 21 continuous with the bottom part 11 into the curved surface which inclines more gently than the ellipse-shaped part 25, the movement of a spoon can be guided and the operativity of a spoon can be improved.

In addition, by providing the second wall portion 22, a plurality of container bodies 2 can be stacked by the first surface portion 31, and the second surface portion 32 does not require an operation of returning the spoon and moves the food to the spoon. It becomes possible to make it.

Also, by providing the flange portion 13, the lid body 3 can be fixed to the container body 2, food can be packaged, and the strength of the container body 2 can be improved. For these reasons, the food container 1 has high usability and can package food.

The present invention is not limited to the above embodiment. In the above-described example, the food container 1 is described as being a packaging container that wraps food inside the container body 2 and the lid body 3, but is not limited thereto. That is, the food container 1 may be repeatedly used as a container for a self-help device or a nursing tool after removing the lid 3 and eating the packaged food. In addition, the food container 1 may not be used for packaging food, and only the container body 2 may be used as a container, that is, tableware.

In addition, the above-described spoon can be used as appropriate even if it has a circular shape, an elliptical shape, a tip crack shape, or the like as long as the center side is indented with respect to the outer edge side. That is, the shape of the spoon is not particularly limited as long as it can shape food. In addition, various modifications can be made without departing from the scope of the present invention.
